I bought 2 batteries for my cordless tools in June 2023. They were sold with 5 years warranty. They are now not at their best, one is not taking charge at all. I have contacted the seller-soono89- twice but have had no response. What can I do to have the working batteries? Cheers


Unless the seller is an authorised retailer of these batteries there is nothing you can do.

 

In future you should buy items like this from a reputable B & M store so a warranty can be enforced.
